With the development of biodiesel industry, the yield of the main by-product crude glycerol, increased year by year. The production of a large amount of crude glycerol not only caused pollution to the environment, but also greatly reduced the market price of refined glycerol. Glycerol was a stable multifunctional compound, which could be used as the raw material for fine chemical synthesis. The conversion glycerol to all kinds of bio-based chemicals by microorganisms has attracted more and more attention because of its environmental protection, sustainable development and other characteristics. In this paper, the aerobic and anaerobic metabolic pathways of glycerol by microbial fermentation were briefly introduced, and the application of the conversion of crude glycerol to 1, 3-propanediol, bioethanol, lactic acid and 1, 3-dihydroxy ketone by microbial fermentation was emphatic analyzed, in order to provide references for the industrial production of platform compounds.

Key words: biodiesel, crud glycerol, microbial consortia, biorefinery, bio-based chemicals
